无法通过ssh连接到github

Question

我试图从我新安装的linux机器上运行带有fluxbox的manjaro,在github上克隆我的一个存储库.我设置了user.name和user.email并上传了正确的ssh密钥.但我总是得到

The authenticity of host 'github.com (192.30.252.129)' can't be established.
RSA key fingerprint is SHA256:nThbg6kXUpJWGl7E1IGOCspRomTxdCARLviKw6E5SY8.
Are you sure you want to continue connecting (yes/no)? 
Host key verification failed.
fatal: Could not read from remote repository.

Please make sure you have the correct access rights and the repository exists.

我google了它,发现我应该做的ssh-keygen -R github.com应该从我的known_hosts文件中删除github但是known_hosts文件还没有存在,因为我刚刚完成了一个新的linux安装.

所以我试过ssh -vT git@github给了我

ssh -vT git@github.com

这是我的头脑.谁能告诉我出了什么问题,也许可以解决这个问题？

您是否尝试将github添加为已知主机？

如果您有一个现有known_hosts文件并且不想覆盖(如评论中建议的@Puce),请使用此文件.

ssh-keyscan -t rsa github.com >> ~/.ssh/known_hosts

这会将rsa密钥添加到known_hosts的末尾.

如果您不知道是什么known_hosts/意味着什么,或者您从未参与其中,那么您可以简单地编写一个新的,但请注意,如果您有任何内容,则会删除现有的.

ssh-keyscan -t rsa github.com > ~/.ssh/known_hosts
